Overview of screening eligibility in patients undergoing ruptured AAA repair from 2003 to 2019 in the Vascular Quality Initiative.

OBJECTIVE: Although efforts such as the Screening Abdominal Aortic Aneurysms Very Efficiently (SAAAVE) Act have improved access to abdominal aortic aneurysm (AAA) screening, certain high-risk populations are currently excluded from the guidelines yet may benefit from screening. We therefore examined all patients who underwent repair of ruptured AAA (rAAA) to characterize those who are ineligible for screening under current guidelines and evaluate the potential impact of these restrictions on their disease. METHODS: We identified patients undergoing rAAA repair in the Vascular Quality Initiative (VQI) database between 2003 and 2019. These patients were stratified by AAA screening eligibility according to the Centers for Medicare and Medicaid reimbursement guidelines. We then described baseline characteristics to identify high-risk features of these cohorts. Groups with disproportionate representation in the screening-ineligible cohort were identified as potential targets of screening expansion. Trends over time in screening eligibility and the proportion of AAA repairs performed for rAAA were also analyzed. RESULTS: A total of 5340 patients underwent rAAA repair. The majority (66%) were screening-ineligible. When characterizing the screening-ineligible group by sex and risk factors (smoking history or family history of AAA), the largest contributors to screening ineligibility were males less than 65 years of age with a smoking history or family history of AAA (25%), males greater than 75 years of age with a smoking history (25%), and females older than 65 years of age with a smoking history (19%). In comparison with rAAAs prior to implementation of the SAAAVE act, the proportion of AAA repair performed for rupture among males undergoing AAA repair in the VQI decreased from 12% to 8% (P < .001), whereas in females, there was no change (P = .990). There was no statically significant difference in screening eligibility for either males (P = .762) or females (P = .335). CONCLUSIONS: Most patients who underwent rAAA repair were ineligible for initial AAA screening or aged out of the screening window. Furthermore, rAAA rates and screening ineligibility have not improved as much as expected since the passage of the SAAAVE Act. Our data suggest that three high-risk populations may benefit from expansion of AAA screening guidelines: males with a smoking history or family history of AAA between ages 55 and 64 years, female smokers older than 65 years, and male smokers older than 75 years who are otherwise in good health. Increased efforts to screen these high-risk populations may increase elective AAA repair and minimize the morbidity and mortality associated with rAAAs.

Diagnostic Yield of Population-Based Screening for Chronic Kidney Disease in Low-Income, Middle-Income, and High-Income Countries.

Importance: Population-based screening for chronic kidney disease (CKD) is sometimes recommended based on the assumption that detecting CKD is associated with beneficial changes in treatment. However, the treatment of CKD is often similar to the treatment of hypertension or diabetes, which commonly coexist with CKD. Objective: To determine the frequency with which population-based screening for CKD is associated with a change in recommended treatment compared with a strategy of measuring blood pressure and assessing glycemia. Design, Setting, and Participants: This cohort study was conducted using data obtained from studies that evaluated CKD in population-based samples from China (2007-2010), India (2010-2014), Mexico (2007-2008), Senegal (2012), and the United States (2009-2014), including a total of 126 242 adults screened for CKD. Data were analyzed from January 2020 to March 2021. Main Outcomes and Measures: The primary definition of CKD was estimated glomerular filtration rate less than 60 mL/min/1.73 m2. For individuals with CKD, the need for a treatment change was defined as not taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker or having blood pressure levels of 140/90 mm Hg or greater. For individuals with CKD who also had diabetes, the need for a treatment change was also defined as having hemoglobin A1c levels of 8% or greater or fasting glucose levels of 178.4 mg/dL (9.9 mmol/L) or greater. Case finding was defined as testing for CKD only in adults with hypertension or diabetes. Results: Among 126 242 adults screened for CKD, there were 47 204 patients in the China cohort, 9817 patients in the India cohort, 51 137 patients in the Mexico cohort, 2441 patients in the Senegal cohort, and 15 643 patients in the US cohort. The mean age of participants was 49.6 years (95% CI, 49.5-49.7 years) in the China cohort, 42.9 years (95% CI, 42.6-43.2 years) in the India cohort, 51.6 years (95% CI, 51.5-51.7 years) in the Mexico cohort, 48.2 years (95% CI, 47.5-48.9 years) in the Senegal cohort, and 47.3 years (95% CI, 46.6-48.0 years) in the US cohort. The proportion of women was 57.3% (95% CI, 56.9%-57.7%) in the China cohort, 53.4% (95% CI, 52.4%-54.4%) in the India cohort, 68.8% (95% CI, 68.4%-69.2%) in the Mexico cohort, 56.0% (95% CI, 54.0%-58.0%) in the Senegal cohort, and 51.9% (51.0%-52.7%) in the US cohort. The prevalence of CKD was 2.5% (95% CI, 2.4%-2.7%) in the China cohort, 2.3% (95% CI, 2.0%-2.6%) in the India cohort, 10.6% (95% CI, 10.3%-10.9%) in the Mexico cohort, 13.1% (95% CI, 11.7%-14.4%) in the Senegal cohort, and 6.8% (95% CI, 6.2%-7.5%) in the US cohort. Screening for CKD was associated with the identification of additional adults whose treatment would change (beyond those identified by measuring blood pressure and glycemia) per 1000 adults: China: 8 adults (95% CI, 8-9 adults); India: 5 adults (95% CI, 4-7 adults); Mexico: 26 adults (95% CI, 24-27 adults); Senegal: 59 adults (95% CI, 50-69 adults); and the US: 19 adults (95% CI, 16-23 adults). Case finding was associated with the identification of 46.2% (95% CI, 45.1%-47.4%) to 86.4% (95% CI, 85.4%-87.3%) of individuals with CKD depending on the country, an increase in the proportion of individuals requiring a treatment change by as much 89.6% (95% CI, 80.4%-99.3%) in the US, and a decrease in the proportion of individuals needing GFR measurements by as much as 57.8% (95% CI, 56.3%-59.3%) in the US. Conclusions and Relevance: This study found that most additional individuals with CKD identified by population-based screening programs did not need a change in treatment compared with a strategy of measuring blood pressure and assessing glycemia and that case finding was more efficient than screening for early detection of CKD.

Coronary artery disease surveillance among childhood, adolescent and young adult cancer survivors: A systematic review and recommendations from the International Late Effects of Childhood Cancer Guideline Harmonization Group.

BACKGROUND: Coronary artery disease (CAD) is a concerning late outcome for cancer survivors. However, uniform surveillance guidelines are lacking. AIM: To harmonise international recommendations for CAD surveillance for survivors of childhood, adolescent and young adult (CAYA) cancers. METHODS: A systematic literature review was performed and evidence graded using the Grading of Recommendations, Assessment, Development and Evaluation criteria. Eligibility included English language studies, a minimum of 20 off-therapy cancer survivors assessed for CAD, and 75% diagnosed prior to age 35 years. All study designs were included, and a multidisciplinary guideline panel formulated and graded recommendations. RESULTS: 32 of 522 identified articles met eligibility criteria. The prevalence of CAD ranged from 0 to 72% and was significantly increased compared to control populations. The risk of CAD was increased among survivors who received radiotherapy exposing the heart, especially at doses ≥15 Gy (moderate-quality evidence). The guideline panel agreed that healthcare providers and CAYA cancer survivors treated with radiotherapy exposing the heart should be counselled about the increased risk for premature CAD. While the evidence is insufficient to support primary screening, monitoring and early management of modifiable cardiovascular risk factors are recommended. Initiation and frequency of surveillance should be based on the intensity of treatment exposures, family history, and presence of co-morbidities but at least by age 40 years and at a minimum of every 5 years. All were strong recommendations. CONCLUSION: These systematically assessed and harmonised recommendations for CAD surveillance will inform care and guide research concerning this critical outcome for CAYA cancer survivors.

Imported SARS-CoV-2 Variant P.1 in Traveler Returning from Brazil to Italy.

We report an imported case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant P.1 detected in an asymptomatic traveler who arrived in Italy on an indirect flight from Brazil. This case shows the risk for introduction of SARS-CoV-2 variants from indirect flights and the need for continued SARS-CoV-2 surveillance.

Impact of changes to national UK Guidance on testing for gestational diabetes screening during a pandemic: a single-centre observational study.

OBJECTIVE: To examine the differences in detection rate for gestational diabetes (GDM) comparing the methodology recommended by the National Institute for Health and Clinical Excellence (NICE) compared with testing described as appropriate during the Covid-19 pandemic by the Royal College of Obstetricians and Gynaecologists (RCOG). DESIGN: Cohort study of women delivering between 1 January 2016 and 1 July 2020. SETTING: London Teaching Hospital. POPULATION: All women delivering between 1 January 2016 and 13 May 2020 and follow up of women screening negative between 1 April 2020 and 13 May 2020. METHODS: Retrospective study of prospectively collected data. MAIN OUTCOME MEASURES: Detection rate of gestational diabetes. RESULTS: Using the RCOG guidance, the overall rate of women identified as having gestational diabetes fell from 7.7% (1853/24168) to 4.2% (35/831)(P = 0.0003). Of 230 women who tested negative according to the RCOG criteria from 1 April to 13 May but who subsequently had an oral glucose tolerance test, 47 (20.4%) were diagnosed as having gestational diabetes according to the NICE criteria. CONCLUSIONS: In our setting, the RCOG Covid-19 gestational diabetes screening regime failed to detect 47 of 82 (57%) women subsequently identified as gestational diabetics, and therefore cannot be recommended for general use. TWEETABLE ABSTRACT: Screening for GDM using RCOG Covid criteria reduced detection rates.

Role of surveillance cultures in infection control.

Hospital-acquired infections are a known menace to the primary disease, for which a patient is admitted. These infections are twenty times more common in developing countries than in the developed ones. Surveillance for colonised patients can be passive or active process. In many hospitals, active surveillance culture for certain sentinel organisms followed by contact precautions for the same is an important part of infection control policy. Specific measures can be taken on early detection of multidrug-resistant organism, allowing prevention of widespread transmission in hospitals. Cultures are the most conventional and economical microbiological method of detection. The cost of active surveillance is a major challenge, especially for developing nations. These nations lack basic infrastructure and have logistic issues. The guidelines regarding this are not very clearly delineated for developing countries. Each hospital has its own challenges and the process is to be tailor-made accordingly. The following review delineates the various aspects of active surveillance for the colonisation of various organisms and the advantages and disadvantages of the same.

Detection of advanced colorectal neoplasia and relative colonoscopy workloads using quantitative faecal immunochemical tests: an observational study exploring the effects of simultaneous adjustment of both sample number and test positivity threshold.

OBJECTIVE: When screening for colorectal cancer (CRC) using quantitative faecal immunochemical tests (FIT), test parameters requiring consideration are the faecal haemoglobin concentration (f-Hb) positivity cut-off and the number of stools sampled. This observational study explored variation in f-Hb between samples and the relationship between sensitivity for advanced neoplasia (AN, cancer or advanced adenoma) and colonoscopy workload across a range of independently-adjusted parameter combinations. DESIGN: Quantitative FIT data (OC-Sensor) were accessed from individuals undergoing personalised colonoscopic screening with an offer of 2-sample FIT in the intervening years. We estimated variation in f-Hb between samples in 12 710 completing 2-sample FIT, plus test positivity rates (colonoscopy workload) and sensitivity for AN according to parameter combinations in 4037 instances where FIT was done in the year preceding colonoscopy. RESULTS: There was large within-subject variability between samples, with the ratio for the second to the first sample f-Hb ranging up to 18-fold for all cases, and up to 56-fold for AN cases. Sensitivity for AN was greatest at lower f-Hb cut-offs and/or using 2-sample FIT. Colonoscopy workload varied according to how parameters were combined. Using different cut-offs for 1-sample FIT and 2-sample FIT to return similar sensitivity, workload was less with 2-sample FIT when the sensitivity goal exceeded 35%. CONCLUSION: Variation in f-Hb between samples is such that both parameters are crucial determinants of sensitivity and workload; independent adjustment of each should be considered. The 2-sample FIT approach is best for detecting advanced adenomas as well as CRC provided that the colonoscopy workload is feasible.

Trends in Low-Value Carotid Imaging in the Veterans Health Administration From 2007 to 2016.

Importance: As part of the Choosing Wisely campaign, primary care, surgery, and neurology societies have identified carotid imaging ordered for screening, preoperative evaluation, and syncope as frequently low value. Objective: To determine the changes in overall and indication-specific rates of carotid imaging following Choosing Wisely recommendations. Design, Setting, and Participants: This serial cross-sectional study compared annual rates of carotid imaging before Choosing Wisely recommendations (ie, 2007 to 2012) and after (ie, 2013 to 2016) among adults receiving care in the Veterans Health Administration (VHA) national health system. Data analysis was performed from April 10, 2019, to November 27, 2019. Exposures: Release of the Choosing Wisely recommendations. Main Outcomes and Measures: Annual rates of overall imaging, imaging ordered for stroke workup, imaging ordered for low-value indications (ie, screening owing to carotid bruit, preoperative evaluation, and syncope). Indications were identified using a text lexicon algorithm based on electronic health record review of a stratified random sample of 1000 free-text imaging orders. The subsequent performance of carotid procedures within 6 months after carotid imaging was assessed. Results: Between 2007 and 2016, 809 071 carotid imaging examinations were identified (mean [SD] age of patients undergoing imaging, 69 [10] years; 776 632 [96%] men), of which 201 467 images (24.9%) were ordered for low-value indications (67 064 [8.2%] for carotid bruit, 25 032 [3.1%] for preoperative evaluation, and 109 400 [13.5%] for syncope), 257 369 (31.8%) for stroke workup, and 350 235 (43.3%) for other indications. Imaging for carotid bruits declined across the study period while there was no significant change in imaging for syncope or preoperative evaluation. Compared with the 6 years before, during the 4 years following Choosing Wisely recommendations, there was no change in the trend for syncope, a small decline in preoperative imaging (post-Choosing Wisely trend, -0.1 [95% CI, -0.1 to <-0.1] images per 10 000 veterans), and a continued but less steep decline in imaging for carotid bruits (post-Choosing Wisely trend, -0.3 [95% CI, -0.3 to -0.2] images per 10 000 veterans). During the study period, 17 689 carotid procedures were identified, of which 3232 (18.3%) were preceded by carotid imaging ordered for low-value indications. Conclusions and Relevance: These findings suggest that Choosing Wisely recommendations were not associated with a meaningful change in low-value carotid imaging in a national integrated health system. To reduce low-value testing and utilization cascades, interventions targeting ordering clinicians are needed to augment the impact of public awareness campaigns.

It was intended to implicate social groups in the search for identification and solution to the problems. RESULTS: the use of participatory diagnosis has provided significant results regarding the importance given by participants to community empowerment in the fight for health, quality of life and social empowerment. FINAL CONSIDERATIONS: participatory research and its relationship to participatory diagnosis favors the understanding of social issues, including health conditions, education and effective participation in problem solving.

Self-reported screening practices of family physicians participating in the colorectal cancer screening program of the canton of Vaud: a cross-sectional study.

BACKGROUND: The organized colorectal cancer (CRC) screening program in the canton of Vaud, Switzerland offers citizens the choice of the faecal immunochemical test (FIT) or colonoscopy via a visit with a family physician (FP). Given the central role of FPs in the program, this study aimed to compare their self-reported preventive practices with the objectives of the program, namely to inform patients about CRC screening and present the choice of colonoscopy and FIT, and to identify factors associated with presenting a choice of tests. METHODS: Mixed-methods study using an online survey and semi-structured interviews. Participants were FPs from the canton of Vaud who had included ≥1 patient in the screening program. We used multivariate logistic regression to compare FPs offering only colonoscopy to those who offered a choice of tests or FIT. RESULTS: The participation rate was 40% (177 respondents / 443 eligible). Most FPs (68%) reported informing more than 75% of eligible patients about the program. Lack of time (n = 86, 33%) was the principal reason cited for not informing patients. Regarding the screening methods, 20% (n = 36) of FPs prescribed only colonoscopy, 13% (n = 23) only FIT and 65% (n = 115) both screening methods. Predictors of offering only colonoscopy rather than a choice of screening tests included: first, FP reporting that they chose/would choose colonoscopy for themselves (OR 8.54 [95% CI 1.83-39.79, P < 0.01]); second, being > 20 years in practice (OR 4.8 [95% CI 1.3-0.17.66, P = 0.02]); and third, seeing 300 or more patients per month (OR 3.05 [95% CI 1.23-7.57, P = 0.02]). When asked what could improve the program, 17% (n = 31) wrote that patients should be informed in advance about the program by postal mail and a large-scale communication campaign. CONCLUSION: The majority of FPs reported CRC screening practices consistent with the objectives of the program. However, to ensure that patients are well informed and to save time, all patients need to be systematically informed about the program. Further, FPs should be encouraged to offer a choice of tests.

Screening for multi-drug-resistant Gram-negative bacteria: what is effective and justifiable?

Effectiveness is a key criterion in assessing the justification of antibiotic resistance interventions. Depending on an intervention's effectiveness, burdens and costs will be more or less justified, which is especially important for large scale population-level interventions with high running costs and pronounced risks to individuals in terms of wellbeing, integrity and autonomy. In this paper, we assess the case of routine hospital screening for multi-drug-resistant Gram-negative bacteria (MDRGN) from this perspective. Utilizing a comparison to screening programs for Methicillin-Resistant Staphylococcus aureus (MRSA) we argue that current screening programmes for MDRGN in low endemic settings should be reconsidered, as its effectiveness is in doubt, while general downsides to screening programs remain. To accomplish justifiable antibiotic stewardship, MDRGN screening should not be viewed as a separate measure, but rather as part of a comprehensive approach. The program should be redesigned to focus on those at risk of developing symptomatic infections with MDRGN rather than merely detecting those colonised.

Use of a highly-sensitive rapid diagnostic test to screen for malaria in pregnancy in Indonesia.

BACKGROUND: The sensitivity of rapid diagnostic tests (RDTs) for malaria is inadequate for detecting low-density, often asymptomatic infections, such as those that can occur when screening pregnant women for malaria. The performance of the Alere™ Ultra-sensitive Malaria Ag Plasmodium falciparum RDT (uRDT) was assessed retrospectively in pregnant women in Indonesia. METHODS: The diagnostic performance of the uRDT and the CareStart™ Malaria HRP2/pLDH VOM (Plasmodium vivax, Plasmodium ovale and Plasmodium malariae) Combo RDT (csRDT) were assessed using 270 stored red blood cell pellets and plasma samples from asymptomatic pregnant women. These included 112 P. falciparum negative and 158 P. falciparum positive samples detected by a composite test (qPCR, LAMP, nPCR) as reference standard. Diagnostic indicators: sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), diagnostic odds ratio (DOR) and the level of agreement (kappa) were calculated for comparison. RESULTS: Compared with the reference test, the uRDT had a sensitivity of 19.6% (95% CI 13.9-26.8) and specificity of 98.2% (93.1-99.7%). The csRDT was 22.8% (16.7-30.3) sensitive and 95.5% (89.4-98.3) specific for P. falciparum infections. Performance of the uRDT was non-significantly different to the csRDT (p = 0.169). RDT outcome was stratified by qPCR cycling threshold (Ct), and performance of the RDTs was found to be comparable across parasite loads. CONCLUSION: The uRDT performed similarly to the currently used csRDTs in detecting P. falciparum infections in asymptomatic pregnant women. In these settings, molecular diagnostics are currently the most sensitive for malaria.

Impact of Guideline-Driven Approach in Follow-Up of Long-Term Complications After Allogeneic Hematopoietic Cell Transplant: Single Center Experience.

OBJECTIVES: After allogeneic stem cell transplant, patients may experience psychiatric, endocrinologic, pulmonary, and cardiovascular problems, as well as secondary malignancies and chronic graft-versus-host disease over the long-term follow-up. These long-term complications not only increase mortality and morbidity of transplant survivors but also decrease their quality of life. In this study, we shared our experiences with our guideline-driven approach for follow-up of long-term complications. MATERIALS AND METHODS: Our study included 91 patients who received allogeneic hematopoietic cell transplant between July 2009 and March 2016 at our medical center. In accordance with the current guidelines, a screening program was applied to all patients seen between February 2016 and February 2017. RESULTS: Median posttransplant follow-up duration was 36 months (range, 12-84 mo), and the median follow-up duration after initial diagnosis was 51 months (range, 15-109 mo). Evaluations of patients posttransplant showed ocular complications (50.6% of patients), oral complications (15.4%), respiratory complications (8.8%), cardiac complications (5.5%), metabolic syndrome (37.4%), liver complications (2.2%), skeletal complications (66.7%), endocrine complications (12.1%), secondary cancers (2.2%), psychosocial adjustment (27.7%), hypertension (5.5%), and type 2 diabetes mellitus (8.8%). CONCLUSIONS: For long-term follow-up, detailed evaluations of body organs and systems are essential. Early recognition of the aforementioned complications could decrease mortality and morbidity. For patients to be monitored by transplant centers over many years, training and awareness should be provided to ensure adequate follow-up of patients. Based on our results, we believe that the long-term follow-up guidelines used in our clinic are applicable to others.

The Potential Population-Level Impact of Different Gonorrhea Screening Strategies in Baltimore and San Francisco: An Exploratory Mathematical Modeling Analysis.

BACKGROUND: Baltimore and San Francisco represent high burden areas for gonorrhea in the United States. We explored different gonorrhea screening strategies and their comparative impact in the 2 cities. METHODS: We used a compartmental transmission model of gonorrhea stratified by sex, sexual orientation, age, and race/ethnicity, calibrated to city-level surveillance data for 2010 to 2017. We analyzed the benefits of 5-year interventions which improved retention in care cascade or increased screening from current levels. We also examined a 1-year outreach screening intervention of high-activity populations. RESULTS: In Baltimore, annual screening of population aged 15 to 24 years was the most efficient of the 5-year interventions with 17.9 additional screening tests (95% credible interval [CrI], 11.8-31.4) needed per infection averted while twice annual screening of the same population averted the most infections (5.4%; 95% CrI, 3.1-8.2%) overall with 25.3 (95% CrI, 19.4-33.4) tests per infection averted. In San Francisco, quarter-annual screening of all men who have sex with men was the most efficient with 16.2 additional (95% CrI, 12.5-44.5) tests needed per infection averted, and it also averted the most infections (10.8%; 95% CrI, 1.2-17.8%). Interventions that reduce loss to follow-up after diagnosis improved outcomes. Depending on the ability of a short-term outreach screening to screen populations at higher acquisition risk, such interventions can offer efficient ways to expand screening coverage. CONCLUSIONS: Data on gonorrhea prevalence distribution and time trends locally would improve the analyses. More focused intervention strategies could increase the impact and efficiency of screening interventions.

Protocolo de implantación de un cribado para la detección precoz del riesgo nutricional en un hospital universitario / Protocol for the implementation of a screening tool for the early detection of nutritional risk in a university hospital

Introducción: La prevalencia de la desnutrición relacionada con la enfermedad en el hospital varía del 20 al 50%. La utilización de herramientas de cribado debe ser el primer paso en la prevención y el tratamiento de los pacientes en riesgo de desnutrición o desnutridos. Objetivos: Implantar un método de cribado nutricional al ingreso en el ámbito de un hospital terciario. Métodos: La Unidad de Nutrición elaboró un protocolo de detección precoz del riesgo nutricional y eligió el NRS 2002 como herramienta de cribado. El protocolo fue aprobado por la Comisión de Protocolos y Procedimientos del hospital y difundido en la intranet. El NRS 2002 se incluyó en el programa de prescripción de dietas para su realización por parte del personal de enfermería de las unidades de hospitalización y como sistema de comunicación directo con la Unidad de Nutrición. Se diseñaron 3 fases para la implantación: fase de pilotaje, fase de implantación y fase de consolidación. Resultados: En la fase de pilotaje se implantó el NRS 2002 en 2 unidades de hospitalización para monitorizar el software. La fase de implantación se realizó en las mismas unidades y se verificaron todos los protocolos de actuación relacionados con el mismo. La fase de consolidación consistió en ir ampliando sucesivamente las unidades de hospitalización con el protocolo implantado. Conclusiones: La implantación de un cribado nutricional al ingreso hospitalario es un proceso largo y complejo, con la implicación de muchos estamentos. El programa informático ha posibilitado que la realización del mismo sea rápido, sencillo y automatizado, y que el resultado del cribado llegue inmediatamente al personal de enfermería de la unidad de Nutrición y se activen los protocolos de actuación de la misma

Introduction: Prevalence of disease-related malnutrition in hospitals ranges from 20%-50%. Use of nutritional screening tools should be the first step in the prevention and treatment of patients at risk of malnutrition and/or undernourished. Aims: To implement a nutritional screening tool at admission to a tertiary hospital. Methods: The nutrition unit prepared a protocol for early detection of nutritional risk and selected the NRS 2002 as screening tool. The protocol was approved by the hospital committee of protocols and procedures and disseminated through the intranet. NRS 2002 was included in the diet prescription software to be implemented by the nursing staff of the hospital wards and as a direct communication system with the nutrition unit. Three phases were designed: pilot phase, implementation phase, and consolidation phase. Results: The pilot phase, NRS 2002 was implemented in 2 hospital units to monitor software. The implementation phase was carried out in the same units, and all action protocols related to it were verified. The consolidation phase consisted of sequential extension of the protocol to the other hospital units. Conclusions: Implementation of nutritional screening at hospital admission is a long and complex process that requires involvement of many stakeholders. Computer software has allowed for a rapid, simple, and automatic process, so that the results of the screening are immediately available to the nursing staff of the nutrition unit and activate the nutritional protocols when required

SARC-F Validation and SARC-F+EBM Derivation in Musculoskeletal Disease: The SPSS-OK Study.

OBJECTIVES: To validate the SARC-F questionnaire for sarcopenia screening in musculoskeletal disease setting, and to assess improvements in diagnostic accuracy by adding "EBM" (elderly and body mass index information) to the SARC-F. DESIGN: Diagnostic accuracy study. SETTING AND PARTICIPANTS: The center involved in this study was located in an urban area of Kobe City, Japan. People with musculoskeletal disease in the knee, hip, or spine who were scheduled for surgical treatment were included. MEASUREMENTS: Sarcopenia was evaluated using the Asian Working Group for Sarcopenia (AWGS) and the European Working Group on Sarcopenia in Older People (EWGSOP2), which included bioimpedance, handgrip strength, and gait speed. Patients answered the SARC-F questionnaire and their body mass index was measured. SARC-F and "EBM" information were combined into an original score. The sensitivities, specificities, and areas under the receiver operating characteristic curve (AUC) were estimated and compared to identify sarcopenia. RESULTS: A total of 959 patients were included. Sarcopenia by AWGS criteria was identified in 36 (3.8%) patients. SARC-F had a sensitivity of 41.7% and specificity of 68.5%. SARC-F+EBM had a sensitivity of 77.8% and specificity of 69.6%, with substantial improvement in sensitivity (P<0.001). The AUCs for SARC-F and SARC-F+EBM were 0.557 (95% confidence interval [CI] 0.452-0.662) and 0.824 (95% CI 0.762-0.886), respectively (P<0.001). Similar results were obtained when EWGSOP2 criteria were used as the reference standard. CONCLUSION: The SARC-F alone is not adequate for finding cases in musculoskeletal disease settings. SARC-F+EBM significantly improved the sensitivity and overall diagnostic accuracy of the SARC-F for screening sarcopenia. SARC-F+EBM is potentially useful for screening sarcopenia in different ethnic and disease settings.

Prevalence of hypertension and cardiovascular risk factors among long-term AIDS survivors: A report from the field.

HIV infection is associated with increased risk and progression of cardiovascular disease (CVD), yet little is known about the prevalence of CVD risk factors among long-term AIDS survivors in resource-limited settings. Using routinely collected data, we conducted a retrospective study to describe the prevalence of CVD risk factors among a cohort of HIV-infected patients followed for over 10 years in Port-au Prince, Haiti. This cohort includes 910 adults who initiated antiretroviral therapy (ART) between 2003 and 2004 and remained in care between 2014 and 2016 when routine screening for CVD risk factors was implemented at a large clinic in Haiti. A total of 397 remained in care ≥10 years and received screening. At ART initiation, 59% were female, median age was 38 years (IQR 33-44), and median CD4 count was 117 cells/mm3 (IQR 34-201). Median follow-up time from ART initiation was 12.1 years (IQR 11.7-12.7). At screening, median CD4 count was 574 cells/mm3 (IQR 378-771), and 84% (282 of 336 screened) had HIV-1 RNA < 1000 copies/mL. Seventy-four percent of patients had at least 1 risk factor including 58% (224/385) with hypertension, 8% (24/297) diabetes, 43% (119/275) hypercholesterolemia, 8% (20/248) active smoking, and 10% (25/245) obesity. Factors associated with hypertension were age (adjusted OR 1.06, P < .001) and weight at screening (adjusted OR 1.02, P = .019). Long-term AIDS survivors have a high prevalence of CVD risk factors, primarily hypertension. Integration of cardiovascular screening and management into routine HIV care is needed to maximize health outcomes among aging HIV patients in resource-limited settings.
